SELF-CLOSING FAUCET.

Application filed December 1, 1920. Serial No. 427,5605

T 0 a whom it may concern Be it known that We,v GEORGE E. Lone, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, andHENRY G. Com)- LEY, a citizen-of the-UnitedStates, residing at GlenRidge in the county of Essex and State of New Jersey, have invente-d'certain new and useful Improvements in Self-Gloss ing Faucets, ofwhichthe following is a description reference being had to the accompanying drawings, forming a part hereof.

Our invention relates to self closing faucets and has for it object toprovide a faucet of the turningplug type which will be simple and inexpensive in construction; readily assembled and. disassembled, in'whi'eh a'single spring serves both to return the. turning plug to closed position andto holdthe plug in its. seat'so as: to take up wear. and prevent leakage. A' further object isv to providethe faucet withineansby which the turningplug may be rotated to open'position.by pressing against it the glass or other receptacle into which liquid is to be drawn.

WVith the obj ectiabove described and other objects hereinafter explained in View our invention consists in the construction and combination of elements hereinafter described and claimed.

Referring to the drawings Figure 1 is a front view of a faucet embo'dying our invention;

I Figure 2 is. a side View of the same;

Figure; 3 is. a longitudinal. central sectional view of the casing, turning'plug and. cap as senibledg.

Figure 6 is afviewof the cap, casing; and plug separated the cap and casing:- being shown; in longitudinal section and the plugbeing shown in elevation; and

Figure 7 is an endview of the turning plug-.

In the. drawings 1" indicatesthe casing, in which the turning plug 2 rotates. The. casing; is provided onone side with a connecting tube, here shownas tapered, internally screwthreaded at i for attachment to the container for the liquid to be drawn off through the faucet and the. casing; has; a

discharge opening5 in its underside and a port or-opening. 6 in its upper part communieating with the interior of the connecting tubev 3.

The casing is open at oneendand tapers from thisope'n end. to an abutment 7 near the other endhaving a central cylindrical opening; 8 through it. Surrounding the opening 8 and extending rearward from the abutment 7 is an annular; flange 10 having its exterior diameter: substantially less than the exterior diameter of the casing so as to leave about its base an annular shoulder 11 the exterior diameter of which is less than that of-the exterior of the casing so as to leave aboutits base abearing 12 for the end of the Wallfor flange 14- of the cap.

13 indicates a. caphaving a flange or Wall 14. adaptedto fit over the. exterior of the annular' shoulder 11. and hear at its end against the bearing 12 and having a central cylindriea-lprojection 15: adapted to fit Within and turn. freely in the central opening 8 in the end of the casing. Through thecentreof this cylindrical projection 15 extends an opening, 1 6 flattened on one side or otherwise made non-cylindrical at its inner end. In the flange or walll i-of the cap is formed a slot 1-7 extending, parallel with the end of the cap to receive the stop pin 18 carried by an arm 19 secured to the casing. A coiled spring. 20 is arranged in the annular space between the exterior ofthe cylindrical projection 15-and. the interior of the wall or,

spring i's soconstructed that, it tendsto 6X pend in. direction parallel with the axis ofthe faucet: and to; also; expand in a directionou'twardfrom the axis. By its tendency toexpand in a. direction parallel with: the aXiSof the: faucet it'acts to force the end of the cap away from the casing and thus, through. the construction. hereinafter explained, draws the turning plug into its seat, and'by its tendency to expand outward from the axisit. acts to force its ends apart and thus to rotate the cap in a direction toturn the plug'2 toclosed position. I

The. turning plug 2 is-tapered to fit the tapered seat. formed in the casing and has at its inner end a central cylindrical projection 25 flattened on one side to fit the opening .16 in the cylindrical projection 15 of the cap, and having in its end. a serewthreaded opening to receii'e a screw 26. This screw 26 is provided with an enlargement 27 which fits and turns freely in a central recess 28 in the outer end of the cap and bears at its inner end against the shoulder The screw is provided with a milled head 30. This screw 26 holds the plug and the cap together so that as the spring 20 presses the cap outward away from the casing it will draw the plug with it and thus force the plug into its seat with a yielding pressure.

Through the turning plug 2 extends, at right angles to its axis, an opening 31 so arranged that its lower end may be brought into register with the discharge opening 5 and with its other end leading to a recess 32 extending across the plug at right angles to its axis and adapted-to be brought into communication with the port or opening 6 to admit liquid from the connecting tube 3.

On its outer end the turning plug is provided with an operating handle having a depending portion 35 extending radially from the line of the axis of the turning plug and preferably in a downward direction, and a portion 36 extending from the outer end of the portion 35 parallel with the axis of the turning plug and towards the other end of the faucet so as to be, when the turning plug is in closed position, directly below the discharge opening 5. By pressing the rim of a glass or other receptacle into which liquid is to be drawn against this portion 36 the handle may be swung rearward to turn the turning plug into open position and permit liquid to flow into the glass or other receptacle.

It'will, of course, be understood that the length of the spring 20 is such, and the stop opening 17 is so arranged that when the stop 18 is in the openin 17 the spring is under tension sufficient t0l0ld the rear end of the stop opening against the stop and thus hold the turning plug in closed position, that is with the lower end of the opening 31 out of line with the discharge opening 5'. When the handle is swung rearward-as above de scribed, the rotation of the turning plug puts the spring 20 under further tension and, when the handle is free to swing for ward, the spring acts to rotate the turning plug back to initial position causing the turning plug to reassume its closed posil tion.

The arm 19 which carries the stop pin 18 is preferably arranged to fit between lugs 35 and 36 on the exterior of the casing and is secured in position by a screw 37.

The slot or opening 17 is formed of sufficient width relative to the diameter of the stop pin 18 to permit the cap to =move towards and away from the casing slightly so as to draw the turning plug into its seat.

Having thus described our invention what we claim is: I

1. In a self-closing faucet the combination of a casing having a tapered seat for the turning .plug open at one end and having an inlet and discharge port, a turning plug extending into the tapered seat in the easing having an opening through it at right angles to its axis having its lower end adapted to be brought into and out of register with the discharge opening by rotation of the plug, acap carried by the casing on theend opposite its open end and rotable thereon, a spring within the cap expansible in a direction parallel with the axis of the casing, and means for holding the cap and turning plug together so that outward movement of the cap will draw the turning plug into its seat.
